Use Of Video Techniques Research Articles

The Mechanism

In The Mechanism, we follow Josefine Baark’s research journey as she seeks to unveil the global networks, games and friendships that resulted in a mechanical tableaux made in China in the 1730s and then brought to Denmark. The film serves two purposes. First to reveal the historical significance of putting objects centre stage in art historical research, even where written documents are lacking. Second, to advance current methodological discussions regarding the use of video techniques for generating research outcomes. The Mechanism argues for a reassessment of cinematic materiality and in correspondence with this, of the research process.

Empathetic technologies: digital materiality and video ethnography

In this article, we advance recent theoretical and methodological discussions regarding the use of video techniques for generating empathetic encounters. We do so through a focus on how these techniques might be rendered in research conducted through sites of action and experience that are explicitly constituted through forms of digital materiality, whereby the digital and material are understood as relational and emergent. We argue for a processual view of digital materiality and in correspondence with this, of the research process, whereby empathetic imagining is itself understood as emergent from the research encounter. By way of example we draw on recent video ethnography research that has used GoPro and researcher-held video recording in collaboration with participants, in order to record and develop understandings of their experiences of self-tracking and cycle commuting.

Wie erleben Eltern und Kinder den Videoeinsatz im ambulant-klinischen Setting?

Video-based observation and behavioural analysis of parent-child-interactions are being used increasingly in clinical diagnostics, parent-child consultation and psychotherapy or in evaluation processes. A multiplicity of publications point out positive aspects of the use of video techniques and demonstrate the value of video recordings for a structured family interaction assessment. There is as yet a lack of systematic research on family members' subjective view of interactions. One topic this paper focuses on is the use of family interaction videos for short term interventions. In a pilot project a questionnaire survey tries to elicit how families perceive this kind of intervention.

Videomediastinoscopy

The use of videotechniques in mediastinoscopy has increased the quality of mediastinal lymph node staging due to improved visualisation and magnification on the screen. The anatomical landmarks are much more easily identified. Teaching with standard mediastinoscopy is difficult as the working channel is small. Videomediastinoscopy has made teaching much easier. It is hoped that videotaping accompanying this article may contribute to standardisation and refinement of this very important and frequently performed procedure. Indications, technique, results and complications are discussed in more detail in the procedure on conventional mediastinoscopy.

Use of video techniques to study the electrochemical activation and corrosion of aluminium alloys

In situ video techniques have been used to examine the galvanostatic initiation of pits on two Al–Mg–Sn–Ga alloys and an Al-In alloy demonstrating the switch-on of the anodic-discharge reaction. Surface magnifications in the range ×25 to ×200 have been employed. Surface effects were studied during electrochemical activation and deactivation of the alloys and during the voltage-oscillation phenomenon observed with Al–In alloys when under discharge in alkaline solutions. Alloys undergoing non-superactive behaviour exhibited a much more crystallographic pitting behaviour than those displaying superactive behaviour, the latter showing much more rounded smooth-sided pits. The time required for battery alloys to activate fully, i.e. switch-on, was related to the number of pits per unit area generated. The formation of hydrogen bubbles during switch-on caused a very noisy voltage transient. The voltage oscillatory behaviour of Al–In under discharge was explained by use of the observation that during voltage rise and fall there was sympathetic growth and dissolution of a surface film. This cyclic film growth and dissolution was proposed to cause the voltage oscillation through its oscillatory effect on the specimen area undergoing corrosion.

Improving management effectiveness by training - the use of video techniques to assist self appraisal

A videotaped assessment center for middle management skills incorporating self appraisal into the feedback process can provide effective training at substantially lower cost than traditional assessment centers. This paper describes one such assessment program and elaborates on its advantages for middle manager development.
